Customer Testimonials

2015 Equinox timing chain slipped during start. Ryan got it right in for inspection and supplied pictures in email showing metal in oil along with bent valves. Matt took a look and suggested a remanufactured engine instead of used as these engines are known for oil consumption and timing chain issues. The remanufactured engine has upgraded high tension rings and more holes in piston for drainage. Their experience and reasonable quote convinced me to this route. They pulled the old one out and put the new one with no code issues. They tested it for 10 miles and it have had no issues to date. Very satisfied with service and good folks.

"Matt did exactly what he said he would do in repairing my boat trailer bearings and installing new bearing buddy's. I'm out of town--- so he picked up trailer-completed work in timely fashion and returned my boat to same location for just a small charge. Thank you again Matt and I'll definitely use your business for my auto + boat needs!
